The invention relates to a preloading oil pressure adjusting device of a single-cylinder type shock absorber. The device comprises a damping rod, a damping spring sleeves the damping rod, an upper blocking piece and a lower blocking piece are respectively arranged on the damping rod corresponding to the upper end and the lower end of the damping spring, the upper blocking piece and the damping rodare fixed together, and the lower blocking piece and the damping rod are in sliding fit. And a threaded section and a nut are arranged on the section of the damping rod below the lower blocking piece. The device is characterized in that an inner sleeve and an outer sleeve are arranged on the damping rod between the lower blocking piece and the threaded section. The outer diameter of the upper section of the outer circle of the outer sleeve is larger than that a first circumferential step of the lower section. The inner diameter of the upper section of the inner circle of the outer sleeve is smaller than a second circumferential step of the lower section. The outer sleeve is in sliding fit with the upper section of the inner sleeve, and the outer sleeve is in sliding fit with the lower section of the inner sleeve. An oil hole is formed in the lower end of one side of the outer sleeve, the inner end of the oil hole communicates with the space between the first circumferential step and the second circumferential step, and the outer end of the oil hole is connected with an oiler. The device is suitable for automobiles or motorcycles. By the adoption of the device, no special tool needs to be additionally arranged, and the adjustment is convenient.

    本发明涉及一种单筒式减震器预载油压调节装置。它包括阻尼杆,阻尼杆上套有减振弹簧,与减振弹簧上下端相应的阻尼杆上分别有上下挡片,上挡片与阻尼杆固定在一起,下挡片与阻尼杆间呈滑动配合。下挡片之下的那段阻尼杆上有螺纹段及螺母。其特点是:下挡片与螺纹段间的阻尼杆上有内套和外套。内套外圆上有上段外径大于其下段第一周向台阶。外套内圆上有上段内径小于其下段的第二周向台阶。外套与内套上段间、外套与内套下段间均呈滑动状配合。外套一侧下端有油孔,油孔里端与所述第一、第二周向台阶之间相通,油孔外端连有注油器。本发明适用于汽车或摩托车上。采用本发明,不需另配专用工具,调节起来比较方便。
